Red Clover Extract Side Effects

The red flowers of the red clover plant are used to prepare extracts for medicinal purposes, including the treatment of bronchitis, menopause and high cholesterol. Red clover has also been linked to creating similar effects in the body as the hormone estrogen, because it contains high levels of isoflavones. Though no major or fatal side effects have been associated with the red clover herb, consult with a healthcare specialist before using any herbal remedies or dietary supplements.

Nausea

Nausea is classified as a mild feeling of discomfort in the upper area of the stomach and is most often said to provoke a sensation to vomit. According to the University of Maryland Medical Center, nausea is a general side effect of using red clover extract. It usually occurs after prolonged use of the herb. A doctor or physician should be seen if persistent nausea occurs with the use of red clover extract.

Headache

Pain that ranges in intensity around the forehead, temples or behind the eyes is typically considered a headache. Headaches may appear around the nape of the neck as well. Headache is classified as a disorder on its own; however, it may also be a symptom or side effect of other disorders. According to the University of Maryland Medical Center, red clover may cause headaches as a side effect of its use, and it should be discontinued if headaches persist or disrupt daily activities.

Risk of Uterine Cancer

Uterine cancer is a commonly diagnosed cancer in women, also known as endometrial cancer, which starts in the lining of the uterus. The National Cancer Institute reported over 43,000 women over the age of 50 have been diagnosed with this type of cancer. According to the National Center for Complementary and Alternative Medicine, red clover may put women at risk for uterine cancer because of the estrogen-like components it possesses, known as isoflavones. The risk may become greater with prolonged use of red clover extract. Additional research is required to determine exactly how red clover's estrogen compound affects the uterus.
